This may seem stupid.. But, I went to check the timing, and I can't get to it. The timing marks are right up against the firewall. So, is there some trick to it? And, I hope you don't have to crawl under a running car to get to it...

The timing marks are right up against the firewall. Ahh - no. There are TDC marks on the crankshaft pulley, but they are intended to be used when setting valve lash. The _timing_ marks, which include TDC and 35º BTDC, are on the _flywheel_ and are visible through a notch in the bellhousing. |

The picture in my book, showed the pulley. thanks! -- brett |

Which brings on another question... I have a 2.7l, with cis converted to megasquirt. The spec shows 5 atdc initial and 38 total. Is this what I should be using? --brett The timing marks are right up against the firewall. Ahh - no.

Which brings on another question... I have a 2.7l, with cis converted to megasquirt. The spec shows 5 atdc initial and 38 total. Well, yes, that's another question, but it is not the essential question. The essential question is: are you sure you've got a 914/6 flywheel? 'Cause 911 flywheels don't have timing marks on the flywheel... If you're using a 911 flywheel, it's smart to put the timing marks there before mating the transmission, using a known TDC and a degree wheel. I can't really answer the rest, but I expect it will depend on whether or not you are using the stock distributor and have appropriate vacuum sources for whatever it needs. And there's a few different kinds of 2,7's with different cams. 38 sounds like a lot, but I don't know if you're expecting this to run on pump gas, and of what octane. Or your altitude. I used to run a lot of advance in the ur-GTI - but I lived at 6000 feet. Makes a difference. |
